- The implementation of a queue in an array, as given in this chapter, uses the variable count to determine whether the queue is empty or full. You can also use the variable count to return the number of elements in the queue. On the other hand, class linkedQueueType does not use such a variable to keep track of the number of elements in the queue. Redefine the class linkedQueueType by adding the variable count to keep track of the number of elements in the queue. Modify the definitions of the functions addQueue and deleteQueue as necessary. Add the function queueCount to return the number of elements in the queue. Also, write a program to test various operations of the class you defined.Using java, answer the following questions about the code below. 1) Create a new function or method that checks to see if an int parameter is present in the list. 2) Create a main() method or JUnit tests to show that your list code functions as intended. (Code) private class Nodeint data;Node next;Node(int data) {this.data = data;this.next = null;}}private Node first;private Node last; public void addToEnd(int data){ Node newNode = new Node(data);if (first == null){first = newNode;last = newNode;} else {last.next = newNode;last = newNode;}}public void printList(){ Node current = first;while (current != null){System.out.print(current.data + " ");current = current.next;}System.out.println();}public static void main(String[] args){node list = new node();list.addToEnd(2);list.addToEnd(4);list.addToEnd(6);list.printList();}}In Java: -Using a BST Interface (Binary Search Tree) -Create a class Disk. Disk contains four fields: model (String), size (int), measure (String, for GB or TB), and performance index (int). -Disk needs a constructor to initialize all fields, a toString method, and an equals. Make the class Comparable and write a compareTo method that compares Disks based on the size of the disk. Make sure your comparison accounts for the fact that some numbers are in GB and some are in TB. Write a method that will return true if the disk is the same size as the parms; parms are the size and measure("GB" or "TB"). Also write a method to create a Comparator which compares Disks based on the performance rating. -The client code should do the following: Write a function called build, which will open the disks.txt file, read in each disk and add it to the BST. For each disk the model is on the first line, and the second line contains the size, measure, and performance index. The BST is passed to build as…
- CODe full java. In this assignment, you will implement a class called ArrayAndArrayList. This class includessome interesting methods for working with Arrays and ArrayLists.For example, the ArrayAndArrayList class has a “findMax” method which finds and returns themax number in a given array. For a defined array: int[] array = {1, 3, 5, 7, 9}, callingfindMax(array) will return 9.There are 4 methods that need to be implemented in the ArrayAndArrayList class:● howMany(int[] array, int element) - Counts the number of occurrences of the givenelement in the given array.● findMax(int[] array) - Finds the max number in the given array.● maxArray(int[] array) - Keeps track of every occurrence of the max number in the givenarray.● swapZero(int[] array) - Puts all of the zeros in the given array, at the end of the givenarray.Each method has been defined for you, but without the code. See the javadoc for each methodfor instructions on what the method is supposed to do and how to write the code. It…Write a Java program that simulates a basic library delivery system. The user of the program will beable to add different types of items to library collection. In your program, as the main data structure,use the generic collection class ArrayList to store String references.Create three instances from ArrayList of String references. The first one will store the types, thesecond one will store the items, and the third one will store the owners of the items. The types areexactly the following: "Book", "DVD", "Magazine". The items and their owners will be read fromthe keyboard.Regarding the matching between an item and its owner, the location (index value) of an item in thelist of items will be the same with the location of its corresponding owner in the list of owners.As the next step, create the fourth instance from ArrayList of String references and call this list asitemsDeliveredByOwners. This last list will store String references to indicate the owners ofthe items (such as the…rite a method called samePosition in a class called StackExt that receives two parameters st1 and st2 of type ArrayStack and a third parameter pos of type int. The method returns true, if stack st1 and st2 contains the same value in position pos. Otherwise, the method returns false. Assume that both stacks st1 and st2 contain same number of elements. Assume that the position of the top element is 0 and increases by 1 for each subsequent element. The elements of both stacks st1 and st2 must remain in the original relative positions in the stacks at the end of the method. Use common stack operations only such as push, pop, peek, isEmpty, constructor and copy constructor. You can create temporary objects of type ArrayStack in your method. Example: top st1: 4 5 3 10 8 st1: 5 9 4 10 1 If the pos is 3, then both stacks contain 10 in position 3. The method returns true. If the pos is 1, then st1 contains 5 and st2 contains 9 in…

Create a generic class with a type parameter that simulates drawing an item at random out of a box. This class could be used for simulating a random drawing. For example, the box might contain Strings representing names written on a slip of paper, or the box might contain Integers representing a random drawing for a lottery based on numeric lottery picks. Create an add method that allows the user of the class to add an object of the specified type along with an isEmpty method that determines whether or not the box is empty. Finally, your class should have a drawItem method that randomly selects an object from the box and returns it. If the user attempts to drawn an item out of an empty box, return null. Write a main method that tests your class.ii. The following is a short snippet of code that simulates rolling a 6-sided dice 100 times. There is an equal chance of rolling any digit from 1 to…This is for python For this assignment, you will write a program to simulate a payroll application. To that effect, you will also create an Employee class, according to the specifications below. Since an Employee list might be large, and individual Employee objects may contain significant information themselves, we store the Employee list as a linked list. Employee class: Attributes • Employee ID: you can use a string – the ID will contain digits and/or hyphens. The ID must be provided during object construction and there should be no mechanism to change it later. • Number of hours worked in a week: a floating-point number. • Hourly pay rate: a floating-point number that represents how much the employee is paid for one hour of work. • Gross wages: a floating-point number that stores the number of hours times the hourly rate. Methods • A constructor (__init__) • Setter methods as needed. • Getter methods as needed. • This class should overload the __str__ or __repr__ methods so that…
- Please help with coding this in Java In this part, you will implement a class edu.ucdenver.morse.Morse that will provide two instance methods: encode(String) and decode(String). Create the class Morse in the package edu.ucdenver.morse Add two private hash maps (instance variables) between strings, to map the encoding representation. One will map the actual character to the sequence of dots and dashes to represent that character. The other will do the reverse mapping. Initialize these maps in the constructor. Implement the instance methods to encode/decode as follows: Implement the encode(String) method, that given a clean string (normat text) will return the Morse Code encoded representation Example: Input String: "Hello World" Output String: "....=.=.-..=.-..=---= .--=---=.-.=.-..=-..=" Implement the decode(String) method, that given the encoded string (Morse Code) will return the clean text representation.
